Abstract

This paper presented circular scanning synthetic aperture radar (SAR) based on circular scanning antenna. The work principle of this scanning radar was described. The variations of synthetic aperture time, azimuth resolution and time-bandwidth product were analyzed. Also a focused imaging algorithm instead of DBS was used to form high resolution image. This algorithm based on Extended Chirp Scaling (ECS) could compensate phase errors with high precision. The versatile image formation flow was composed of burst imaging, geometric correction and mosaicking. The computer simulation results confirmed that the versatile image formation flow could be used to image precisely for circular scanning SAR.
